A plurality of generally vertical stem walls engage an underside of the false floor panel to support the panel.
Description
- The present invention deals broadly with the field of animal husbandry. More narrowly, however, it deals with waste management and processing of byproducts of animal husbandry. Specifically, the invention deals with treating manure so as to create usable, marketable, solid and liquid fractions. Concurrently, the invention can be used to improve the air quality in an enclosure in which cattle or similar animals are captured.
- Typically, animal husbandry, while conceded as a necessary field of endeavor, has been considered unsavory because of the deleterious odors resulting from biological waste. Air quality as a result of manure defecated by the animals being maintained has been deemed to be a very negative byproduct of the field. This negative view is generally accepted irrespective of the type of animal being attended to by feeding operations. Various types of edifices have been employed for feeding poultry, swine and dairy cattle. It will be understood that, while much of the discussion herein applies where all types of animals can be fed, the specific focus of the discussion will be dairy cattle because of relatively unique characteristics of bovine manure.
- The negative perceptions of product processing and waste management are fueled by environmental, economic, public health and animal health concerns. Given proper attention, however, steps have come to be performed to improve air quality for the animals fed in the building. Flushing the floors of the barns twice each day is one step that can be taken. The situation can also be improved by reducing emissions as a result of the taking of manure in a fresh state. Further, the situation can be improved upon by optimizing nutrient capture.
- Probably the most common concern in conducting feeding operations is the effects of manure from the animals. This is particularly true in the case of cattle which discharge methane gas. Methane gas can build up over time and create a situation that is unhealthy. Breathing the methane gas has been shown to be unhealthy for both the animals and the employees.
- The prior art typically employs a system wherein manure is built up in the barn and is occasionally scraped or falls in between slats where buildup over time occurs. Hydrogen sulfide is produced as a result of fermentation of sulfur-containing compounds and excreted by the animals. Hydrocarbons may react with other atmospheric gasses in the presence of some light to form O3, a critical pollutant. Because of the concerns which arise as a result of the formation of O3, dry pulverized manure will permeate the air.
- Problems are frequently encountered with regard to flushing and diffusing manure. While the manure should be liquefied to some extent, the situation is such that, while one area of the processing equipment will have a high density of manure, other areas will be devoid of any manure. This will result in cattle being stressed and render their meat in an inferior state.
- It is recognized that what is needed is a system which provides economic, environmental and social benefits at the local, regional, national and eventually global levels. It is to these problems and shortcomings of the prior art that the present invention is directed. Features of the invention and advantages obtained in view of these features will become appreciated with reference to the Description of the Invention, drawing figures and appended claims.
- The present invention is an enclosure for capturing and holding cattle or other similar animals. It also functions to retain those animals within a wall defining the enclosure. The enclosure includes a false floor panel which has a multiplicity of orifices formed therethrough. It also has a generally horizontal surface which provides support for the animals. The enclosure or pen has a generally planar surface which is angled downwardly relative to the generally horizontal surface of the false floor. A plurality of generally vertical stem walls are employed. The stem walls function to engage an underside of the false floor panel. The panel is, thereby, supported by the stem walls.
- In one embodiment of the invention, the stem walls are substantially parallel to one another. The stem walls, with said subfloor, define a plurality of lanes which extend downwardly from the false floor panel. It is envisioned that the generally planar surface of the subfloor is angled downwardly relative to the horizontal surface of the false floor at a one percent slope.
- In the preferred embodiment, the false floor takes the form a plurality of generally parallel slats. In that embodiment, a number of adjacent slats are spaced from each other to define the orifices.
- An end wall can be provided. If an end wall is included, it is intended that it intersect generally perpendicularly a plurality of stem walls.
- The present invention is thus an improved waste management system. Further details of the invention and advantages obtained in view of those additional disclosures will become apparent with reference to the Detailed Description of the Invention and claims.
-
FIG. 1 is a top plan view of the geography of the present invention; -
FIG. 1A is a view taken from a part of what is illustrated inFIG. 1 ; -
FIG. 2 is a side elevational view illustrating the structure of a barn in accordance with the present invention; -
FIG. 3 is a view similar toFIG. 2 ; -
FIG. 4 is a side elevational view of a drain system in accordance with the present invention; and -
FIG. 5 is a side sectional view illustrating the floor construction illustrating an enclosure in accordance with the present invention. - Referring now to the drawing figures wherein like reference numerals denote like elements throughout the several views,
FIG. 1 illustrates anoverall system 10 for feeding, as illustrated in the various figures, a large number ofcattle 12, protecting the health of both the cattle and employees of thefeedlot 14 on which thecattle 12 feed, and processing solid and liquid waste voided by the cattle to render such components useful and commercially practical. Included in the system is acattle barn 16, the structure of which will be discussed in more depth hereinafter. Preliminary treatment of manure and other waste products does, however, occur in thecattle barn 16 before being conveyed to aslurry processing site 18. At this site, solid waste and liquid waste are separated for further packaging and use. Ultimately, the slurry passes to a collection area where it can be maintained. - Returning to the feedlot portion of the
system 10, it can be seen that a plurality offootings 20 are embedded in theground 22 at locations that generally approximate the shape, in plan, of thefeedlot 14. At a location elevated with respect to theground surface 22 is afalse floor panel 24. Thispanel 24 has a generallyhorizontal surface 26 which provides support for theanimals 12 at thefeedlot 14. A multiplicity oforifices 28 are defined in thefalse floor panel 24 for purposes as will be seen hereinafter. -
FIGS. 2 and 3 show a number ofcattle 12 positioned on thefalse floor panel 24. A number of thecattle 12 are eating nutrient materials. It follows that bovine manure is deposited on thefalse floor panel 24 bycattle 12 mounted on thatpanel 24. Prior art structures envision flushing a surface 30 on which manure is deposited. The shortcomings of the prior art, however, preclude economization and optimization of processing. In accordance with the present invention, manure, while possibly being disproportionately spread on thefalse floor panel 24, is flushed by water dispensed throughvalves 32 mounted inend walls 48 directing the slurry-producing water across thesurface 26 of thefalse floor panel 24. As a result, the manure is liquefied to a desired degree so that the slurry can spread out fairly uniformly across thepanel 24 before passing through theorifices 28. - As best seen in
FIG. 5 , a subfloor 34 is positioned beneath thefalse floor panel 24. The subfloor 34 includes a generallyplanar surface 36 that is angled downwardly relative to the generallyhorizontal surface 26 of thefalse floor 24. The downward angling of thesubfloor surface 26 is exaggerated for purposes of understanding the invention. It will be understood, however, that the downward angling may be as little as one percent. That is, for every 100 feet of distance along the subfloor, there will be a downward deflection of one foot. This construction not only allows for dispersion of manure across the subfloor 34, but it also provides for down-flow of the slurry to adrain 38 positioned at the bottom of the subfloor 34. - It has been found desirable to divide the subfloor 34 into a plurality of
lanes 40, each having a width significantly less than the width of the subfloor 34. By providing such a construction, dispersion of manure can be further facilitated. - The
lanes 40 are formed by stem walls 42 which can be substantially parallel to one another. Integrity is given to thelanes 40 by defining the lanes with the subfloor 34 in conjunction with the stem walls 42. - The plurality of generally vertical stem walls 42 typically engages an
underside 44 of thefalse floor panel 24. Thefalse floor panel 24 is, thereby, to support thecattle 12 and be supported by the stem walls 42. - The
false floor panel 24 would typically comprise a plurality of generallyparallel slats 46. In a number of spaces, theslats 46 are spaced from each other to defineorifices 28 or slots therebetween. Again, theorifices 28 provide spraying of water across the generallyhorizontal surface 26 of thefalse floor panel 24. - It will be understood that the invention is intended to include a completely subterranean flow path.
- It will also be understood that this disclosure, in many respects, is only illustrative. Changes may be made in details, particularly in matters of shape, size, material, and arrangement of parts without exceeding the scope of the invention. Accordingly, the scope of the invention is as defined in the language of the appended claims.
